E PECIFICATION forming part of Letters Patent No. 364,118, dated May 31, 1887.

Application filed May an, 1826.

To all whom, it may concern.- I

Be it known that we, MATHEW W. LEONARD and DAVID M. LEONARD, citizens of the United States, residing at Utica, in the county of Seward and State of Nebraska, have invented a new and useful Improvementin Check-Rowers, of which the following is a specification.

Our invention relates to improvements in cheek-rowers for corn-planters; and it consists of the peculiar combination and novel construction and arrangement of the various parts for service, substantially as hereinafter fully set forth, and particularly pointed out in the claim.

Inthe accompanying drawings, Figure 1 is a perspective view of a check-rower for cornplanters embodying our invention. Fig. 2 is a vertical sectional view on an enlarged scale through the locking device or brake.

Referring to the drawings, in which like letters of reference denote corresponding parts in both the figures, A designates the carrying beam of a corn-planter of any preferred or well-known class, which, however, we have not shown herein, as our invention can be applied to corn-planters of different construetions that are operated by check-wires. The carrying-beam is. secured upon the cornplanter in the well-known manner-and place, and at its ends it is provided with arms B, which are rigidly secured in place by bolts or other like or equivalent means. These arms are braced and strengthened by inclined brace rods or bars I), and at their extremities the 'arms are provided with supporting brackets D and E, which are rigidly secured in place, The bracket D extends from the arm in one direction, and is provided with a single guideroller, (1, that is loosely journaled therein, and the bracket E extends fromits arms in the opposite or reverse direction and carries two friction or guiderollers, e, which are arranged a suitable interval apart and loosely journaled in suitable pins or shafts, so that they are free to rotate under the force of the check-wire and the buttons or, stops thereon.

F designates the rotary shaft that is arranged longitudinally of the beam A, and journaled at its ends in suitable bearings or boxes, f, se-

cured to the arms 13, and the middle of the said shaft is supported or joprnaled in a hanger,

that is loosely journaled on a pin or shaft that is carried'by one end of an oscillating arm or lever, H. This lever H is pivoted at or near its middle to a lug, e, of a supporting-plate, I, suitably secured on the carrying-beam A, and the opposite end of the lever on which the friction-roller is' journaled is bent or inclined at an angle to the other end and slotted 1ongitudinally, as shown, pin is passed through this slot to secure the lever to a reciprocating seedslide, which, however, we have not shown herein, as it may be of any construction desired, and this bolt may be moved in the slot to vary the stroke or length of movement of the slide, and thus regulate the quantity ofseed dropped or sown.

of the latter can be regulated as above men tioned.

The ends of the rotary shaft F carry the radial tappet-arms J, which are formed in a single piece of metal and arranged at substantially rightangles to each other. The arms are suitably secured upon the extremities of the shaft exterior to the standards thereon, and the free outer ends of the arms are slotted or bifurcated to provide the laterally-yielding fingers j, which are bent or flared outwardly to permit of the free passage of the buttons or stops of the check-wire, as is obvious.

Y K designates our improved brake or locking device for retarding the motion of the shaft F simultaneously with the time when the balls of the check-wire leave the arms J, which is 1.. new" that is secured to the back plate and passes through the lever, the outer end of the guide pin being threaded and provided with a binding or clamping nut, m, that bears against the pivoted lever and serves to force the latter inwardly against the tension of a retractingspring, m, that encircles the guide-pin and bears against the pivoted lever and the nut to normally force the lever toward the plate. The rotary shaft F carries a disk, N, which is provided with a series of projections or protuberances, n, and the friction-roller of the pivoted lever is grooved at its periphery and receives the projections of the disk N, the edges of the disk intermediate of the projections being curved, as shown, so that the friction-roller can ride freely over the disk and force or actuate the pivoted lever outwardly and inwardly against and under the tension of the coiled retracting-spring.

The operation of our invention is obvious. The wires of the check-row pass between the friction-rollers of the brackets D and E and between the fingers of the tappet-arms to rotate the latter and the shaft F, so that the camwheel G will be revolved to actuate the pivoted lever H, and thus actuate the seed-slide. The disk N, with its projections, will also be revolved with the shaft, so that the projections Will force the lower end of the pivoted lever L away from the shaft and against the tension of the spring, and when the projections successively pass the friction-roller and are out of and consequently on the disk N of the shaft.

Although we have shown the disk N as pro- 5 vided with four radial projections or protuberances, so that the revolutions of the shaft F are checked to a sufficient degree at every onequarter revolution, still the number of the protuberances can be varied to check the shaft at every one-half of a revolution or any other fractional part thereof, as is obvious.

The improvements are simple and strong in construction, and they can be readily applied to check-rower corn-planters of any preferred class.

Slight changes in the form and proportion of parts can be made without departing from the spirit of our invention.

The protuberances in the rotating disk N engage with the brake simultaneously with the time when the tappets of the check-wire leave the t'appet-arms, so that the arms are prevented from going too far.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The combination ofa carrying-beam, abracket-plate, I, afiixed thereto and having a depending arm, a vertically-disposed lever, H, pivoted to the arm of the plate and carrying a friction-roller at one end and having a longitudinal slot at its lower end, through which is passed a bolt to adj ustab] y connect the lever with the seed-slide, and a rotary shaft having acam-wheel provided with aserpentine groove, in which the friction-roller of the lever works, substantially as described.

In testimony that we claim the foregoing as our own we have hereto afiixed our signatn res in presence of two witnesses.
